Technical Field
[0001] The utility model relates to processing equipment, in particular to a device used for boring processing. Background Art
[0002] In the construction process of single-shaft or multi-shaft combined cycle units of F-class or above gas turbines, due to the different specifications and manufacturing and production subsidiaries of the main equipment, there will be a small amount of misalignment in the inner diameter of the equipment coupling bolt hole. It is necessary to use boring equipment to grind the corresponding bolt holes before the two sets of couplings are finally connected, that is, boring the coupling bolt holes to eliminate the inner diameter misalignment between the coupling bolt holes. The existing factory-supplied reamer is manually operated and uses diamond grinding discs as reamer. It has no variable speed adjustment function, and the assembly and layout need to be adjusted in many ways according to the actual conditions on site and fixed tooling needs to be made. At the same time, more manpower is invested on site and the efficiency is slow. Utility Model Content

If the boring span is too long, the boring accuracy affected by the vibration of the boring bar can be eliminated; the rotary driver and the boring bar are installed on the support frame, and the boring tool is installed on the boring bar, and the boring bar is centered to ensure the boring accuracy; then, the screw rod and the feed controller are installed. After installation, start the drive motor, drive the boring bar to rotate through the rotating driver, and control the feed controller at the same time. On the one hand, the boring bar and the boring cutter on it are driven to rotate through the rotating driver, so as to bore the through hole on the equipment; on the other hand, the feed controller controls the rotation of the screw rod, and because the screw rod is fixed in the axial direction and cannot move, the feed controller is also connected to the boring bar and cannot rotate relative to the screw rod, so that the feed controller drives the boring bar to move along the axial direction of the screw rod, that is, drives the boring cutter to move along the through hole of the equipment, and realizes the boring processing of the entire through hole. Its beneficial effect is that this kind of boring device uses a motor to control the rotation of the boring bar and a feed controller to control the movement of the boring cutter, which is conducive to improving the processing accuracy and work efficiency, and its structure is simple and easy to operate. A modular structure is formed between the various components, and installation, disassembly and transportation are extremely convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0017] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial...), then the directional indication is only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
[0018] If there are descriptions involving "first" or "second" in the embodiments of the utility model, the descriptions of "first" or "second" are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.
[0019] The utility model provides a boring device.
[0020] The boring device of this embodiment includes a fixedly mounted support frame 1, on which a rotary driver is fixedly mounted, a boring rod 4 for mounting a boring tool is connected to the rotary driver and rotates with the rotary driver, and the boring rod can move axially relative to the rotary driver, and there is also a lead screw 5 rotating around a fixed axis and a feed controller 6 screwed to the lead screw and driving it to rotate, the axis of the lead screw is parallel to the axial direction of the boring rod, and the feed controller is rotatably connected to the boring rod and relatively fixed along the axial direction.
[0021] The boring device, the rotary driver comprises a transmission box 2 and a drive motor 3, the transmission box is mounted on the support frame 1 and connected to the boring bar, the drive motor is connected to the transmission box and drives the boring bar to rotate through the transmission box.
[0022] like Figure 1 , 2As shown in the figure, the support frame is fixedly installed on the equipment to be bored, and is designed as a complete set of assembly parts, which can complete the assembly work quickly and efficiently. At the same time, it is designed as a front and rear clamping plate structure to improve the connection stability and working accuracy. If the boring span is too long, the boring accuracy affected by the vibration of the boring bar can be eliminated; the rotary drive and boring bar are installed on the support frame, and the boring tool is installed on the boring bar, and the boring bar is centered to ensure the boring accuracy; then, the screw and feed controller are installed. After installation, start the drive motor, and drive the boring bar to rotate by rotating the driver, while controlling the feed controller. On the one hand, the boring bar and the boring cutter thereon are driven to rotate by rotating the driver, thereby boring the through hole on the equipment; on the other hand, the feed controller controls the rotation of the lead screw, and because the lead screw is fixed in the axial direction and cannot move, the feed controller is also connected to the boring bar and cannot rotate relative to the lead screw, thereby making the feed controller drive the boring bar to move along the axial direction of the lead screw, that is, driving the boring cutter to move along the through hole of the equipment, thereby realizing the boring process of the entire through hole.
[0023] In the boring device, the support frame 1 can be detachably mounted on the device to be bored, for example, by a clamping mechanism that can be clamped and fixed on the device to be bored, or by a connecting member such as a bolt. In addition, a universal self-aligning bearing is mounted on the support frame 1, through which the gap between the support frame 1 and the boring bar can be effectively adjusted, and the working stability is good, which is conducive to improving the processing accuracy.
[0024] The driving motor 3 of the boring device is a speed-adjustable motor that can rotate in both directions to change the boring speed and realize functions such as forward and reverse rotation. The boring rod 4 is a hollow structure, which can reduce the weight while ensuring the structural strength, thereby achieving maximum shock absorption. In addition, the screw 5 can be rotatably mounted on the feed controller 6 and the rotary drive-the spindle box housing, which can make the structure of the boring device more compact and can also effectively improve the convenience of assembly and disassembly, working stability and processing accuracy. In addition, the feed controller 6 can be equipped with a feed handwheel for controlling the feed speed to facilitate manual feeding and achieve stepless speed regulation.
[0025] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model.
